2' Claims. 1

'Ihisv invention relates to shoes of. the platform type and to a novelmethod of making the same.

In accordance with thisV invention, I cover the platform sole with acovering made in two se'ctions, viz., a forepart section and la heelsection, which are overlapped upon one another in the region -of theheel breast, or' in case a wedge is used, at a slightly forward positiontoward ball.

In the forepart area of my shoe, I use an insole which has astitch-receiving lip sewed around its margin or channeled as close tothe edge of the insole as is possible without having the stitches pullthrough. This not only enables me to neatly stitch the forepart sectionof theV platform cover to the insole lip and upper structure by a singlerow of stitching, but to use for this stitching step a conventional weltsewing machine, or machines especially adapted for this type of work,such as the Puritan or Union lock-stitch sewing machines.

When so stitched, the forepart section ofthe platform cover takes theplace of the welt used in the ordinary welt shoe, after the. unstitchedportion of said cover section has been pulled down tightly over andcemented vto the outer-edge of the platform sole and iirmly fastenedagainst. the bottom face of said sole, as by cementing.

In the heel area, of my shoe, the heel section of the platform cover isdrawn around the outer edge of the platform sole and rmly fastenedagainst both the top and bottom faces of said platform sole, usingconventional heel seat lasting equipment, either hand or machine method.

Thus, I provide a platform shoe of extremely neat and attractiveappearance and excellent wearing qualities which can be made on standardequipment at minimum cost.

In the accompanying drawing wherein I have shown a preferred embodimentof my invention:

Figure 1 is a side elevation of a shoe made in accordance with mymethod, and

Figures 2 and 3 are enlarged cross-sections on the lines 2 2 and 3-3respectively, of Figure 1.

The upper structure of my shoe is conventional, comprising a vamp I0,quarters II, lining I2, counter I3, and cushion heel pad I4.

In the forepart of my shoe I place an insole I5 which may or may nothave Gem cloth or its equivalent I@ cemented to the under face thereof.Stitched at I8 to the insole or channeled as closely as safely possibleto the margin thereof is a stitch-receiving lipor rib I'I.

In the bottom of the shoe I place conventional filler material I3 and aplatform sole 20.

Platform 26 is covered by a sectional cover or wrapper, of leather orany other suitable material, consisting of a, forepart section 2l and aheel section 2. Section 2`I is applied as a continuous strip beginningat the point marked 22 iin Figure 1 and extending around the forepart ofthe platform sole to a point (not shown) approximately opposite pointZ2, and section 21 is likewise applied'fa's fa continuous stripextending around the heel part of the platform sole and overlappedbysection 2'I in the region of the heel breast.

Cover section 2| iszstitched near its Vupper edge as at' 23 to the.`upper and lip I'I on any Icnnventional .sewing machine. The freeportion of the cover is drawn downwardly around the outer edge of theplatform and bent inwardly and fastened. against; the bottom face of theplatform asat 211.

In the heel .region of the shoe, the quarters II, lining I2, and counterI3 are drawn beneath the insole on a conventional heel seatA lastingmachine.

The outsole. 25; with its cover section 2T and platform 20 are nailed orcemented together as at: 26, amhe'el lift 28 and heel 2S are nailed tothe overlying parts as at 30'.

In making my shoe, I prefer to proceed as follows:

The upper of the shoe is put together in the conventional manner, eitherlined or unlined, and either with or without a counter pocket andcounter.

The insole I5, constructed with lip I'l sewed or channeled as closely aspossible to its edge without having the stitches pull through, andprovided either with or without Gem duck, is next tacked in position onthe bottom of the last, after which the upper is pulled over andside-lasted, and the toe and heel seat then wiped in the conventionalmanner, in case a wedge is used, the shank is lasted fiat as far asnecessary.

Next the forepart section 2I of the platform cover is sewed at its upperedge to the upper and to the lip I'I of the insole in a conventionalwelt sewing machine, or by means of machines especially adapted for thistype of work, such as the Puritan or Union lock-stitch sewing machine.This leaves the free part of cover section 2| projecting beyond theinseam.

The surplus material may now be trimmed from below the seam as close asis safe, and the filler, which may be solid, thermoplastic,spongerubber, or so-called cold ller, is then applied in a thicknessequal to the height of the inseam.

The platform, attached to the wedge if a wedge is used and which haspreviously been rounded to the proper size to give the desiredextension, is now covered at the heel part by cover section 21 in such away as to be slightly lapped in the region of the points marked 22 whenthe platform is laid properly on the bottom of the shoe.

Cement is now applied to the inner surface of cover section 2l and ifdesired the margin of the platform section 2|, and the free portion ofthe cover section is then pulled tightly down over the edge of theplatform and firmly pressed against the under face of the platform. Inthe heel region of the shoe, the free edges of cover section 21 lieagainst the adjacent surfaces of the upper structure and platform sole,respectively, and are fastened by the lines of nails 26 and 3U, as wellas by cementing if desired.

The outsole may be attached either by the cement process or may be sewedthrough the insole either Littleway or McKay stitched, and either aloftor in a channel.

If the shoe has a Wedge heel, the outsole lies perfectly fiat across thebottom of the shoe.

If the heel is of the conventional type, or spring heel, orsquare-breasted heel, then it is applied afterwards in the ordinary way.

My method may be applied to wedge type shoes, with at outsoles, bysimply covering the rear section of the wedge with a, separate coverpiece so that I get a slight lap at the joint 22 with the forepart coversection 2|.

1f desired, I may first adhere the platform and ller to each other andthen assemble them in the shoe, or I may construct these parts in onepiece and provide them with an offset edge.

While I have described and illustrated a preferred embodiment of myinvention and a preferred method of making the same, I realize that theconstruction and procedure described may be changedsomewhat asrequirements may demand. All such Changes are to be regarded as withinthe purview of my invention if within the spirit and scope of theappended claims.

I claim:

1. A platform shoe comprising an upper structure, an insole having amarginal stitch-receiving lip, a platform sole, an outsole, a heel lift,a heel, and a, sectional platform cover comprising overlapping forepartand heel sections, a line of stitching passing through the upper edge ofthe forepart section of said platform cover, the lower edge of the upperstructure, and said stitchreceiving lip of the insole for fastening saidparts together, the portion of the platform cover which is not stitchedto said lip and upper structure extending around the edge of theplatform sole and being inturned to lie between the platform sole andthe outsole, a line of nails in the heel area of the shoe passingthrough said heel, heel lift, outsole, platform sole and the heelsection of said platform cover for fastening said parts to the upperstructure, and a separate line of nails in the heel area of the shoepassing through the outsole, the platform sole, and the heel section ofsaid platform cover for fastening said parts to the insole.

2. The steps in the method of making a platform shoe, which compriseassembling together an upper structure, an insole having a marginalstitch-receiving lip, a platform sole, an outsole, a heel lift, and aheel, applying a sectional platform cover comprising overlappingforepart and heel sections to the platform sole, stitching the upperedge of the forepart section of said cover to the insole lip and to theadjacent lower portion of the upper structure, drawing the un- Stitchedportion of said forepart section around the edge of the platform soleand fastening it against the bottom of the platform sole, nailing theheel, the heel lift, the outsole, the platform sole and the heel sectionof the platform cover to the upper structure, and separately nailing theoutsole, the platform sole and the heel section of the platform cover tothe insole.
